Did you try the table and put it inside the central space from post number 28

It will save you a lot of headaches (below the breadcrumb row has been removed).
Code:
<!-- central space -->
<table>
<!-- TR picture and vid row (2cols) -->
<tr>
<td> <!-- TD cell 1 picture -->
<img src="img/partner.jpg"/>
</td>
<td bgcolor="#FF0000"> <!-- TD cell 2 vid -->
<object width="150" height="125"><param name="movie" value="http://www.youtube.com/v/4g9Mqs-Pw2o&hl=en&rel=0"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/4g9Mqs-Pw2o&hl=en&rel=0" type="application/x-shockwave-flash" wmode="transparent" width="150" height="125"></embed></object>
</td>
</tr>
<!-- TR text row (2cols combined) -->
<tr>
<td colspan="2">some loads of text</td>
</tr>
</table>
<!-- /central space -->
